Precision bearings, angular contact ball bearing installed in pairs

The lubrication effect is good or bad in addition to the lubricant itself performance and lubrication method, bearing lubrication is the main structural design factors, the number of the oil hole, size, location, directly affect the lubrication effect, backing bearings and lubrication design should be confirmed before the lubricant performance way. Fatigue fracture bearing ring ( Especially outer ring) Under the alternating load and impact load, the stress incurred by the continuously exceed the material fatigue strength limit lead to the generation of fatigue crack, crack extension to the amount eventually lead to parts of the stress fracture. Remove the bearing from the play dough, cover or poor bearing cover assembly, should be reassemble, make on both ends of the cover and base cooperate good seam allowance, and diagonal tighten the bolt of the bearing cover. According to the types of inclusions can be divided into: type A ( Sulfide) , type B ( Alumina) , C ( Silicate) And type D ( Dot deformation) And Ds class ( Large particle inclusions ( Inclusion of microns in diameter) 。 The purpose of the determination of the motor shaft voltage is to know the size of the motor shaft current. Determine the purpose of the motor shaft current is obtained directly through the motor bearing current value. After, according to the understanding of the release bearing use, tell everybody the car engine timing kit, clutch kit, etc. , as long as meet the replacement mileage or fixed number of year, even after replacement and no problems, also want to replace all, otherwise easy to appear the situation in that case! Therefore, we in the process of repair cars, some still need to listen to the teacher's advice, maintenance to avoid again soon to repair the car. Prohibit slanting inclined condole, inner and outer ring of bearing demand bidirectional is one-way axial fastening, swimming or axial, depending on the limit requirements of the support and the type of bearing is used. Double row doubelrowsin - one-way thrust ball bearings Methyl amino acetonitrile gle - 方向, Methyl amino acetonitrile thrustballbearin - Methyl amino acetonitrile g has double concentric raceway and load the one-way thrust ball bearings under the same direction. Railway vehicles in recent years, using foam outsourcing towel sets of oil volume, on the bus, the axial force on the bearing the guard on the inside and outside the circle, under which without a guard on the locomotive bearing, axial force on the ball bearing on the shaft end. Open the back cover, first with a mark stroke shaft and motor shell, with shaft encoder activity base, encoder activity base line of movable ring and motor shell. The other side of the bearing is relatively simple, and simple in the front wheel bearing samples, bearing installed must check the bearing inner ring and the shaft shoulder clearance ( With no clearance as well) , after the motor has cover, still need to test the hall, found the ball or roller rack and other serious wear, corrosion and metal peeling should be replaced. Determine the speed range according to the requirements of the extrusion process, the screw rotation speed in the range should be adjustable, and try to realize stepless speed regulation.
